  • Publication number: 20240131965
    Abstract: It is provided an adjustment device for a vehicle subassembly comprises a guide rail which extends along a longitudinal direction, an adjustment assembly which is guided on the guide rail so as to be displaceable along the longitudinal direction and which is assigned to the vehicle subassembly, a spindle which is arranged on the guide rail, and an adjustment mechanism which is operatively connected to the spindle, is arranged on the adjustment assembly and has a mechanism housing and is able to be driven so that the adjustment mechanism can be displaced, together with the adjustment assembly, along the longitudinal direction relative to the guide rail. On the adjustment assembly there is arranged at least one retaining element, which has an opening which is delimited by an edge and through which the spindle extends.

  • Publication number: 20230157847
    Abstract: A prosthetic wrist unit providing a connection between the arm and a hand mechanism, comprising a wrist base unit with at least one connection slot into which the hand mechanism is to be inserted and at least one connecting piece enabling the rotational movement of the prosthetic wrist unit; a joint including a joint seat and a joint body; a locking mechanism comprising a locking mechanism opening into which the joint body is inserted and enabling the prosthetic wrist unit to operate in two positions, i.e., fixed or movable; an arm coupling unit into which the joint and the locking mechanism are inserted and which restricts the movement of the joint and the locking mechanism; and at least one tendon ensuring the joint stiffness of the prosthetic wrist unit.

  • Patent number: 10566145
    Abstract: A TiO2-graphene-silver hybrid nanocomposite and a method of preparing the TiO2-graphene-silver hybrid nanocomposite is disclosed. The TiO2-graphene-silver hybrid nanocomposite at an average particle size ranging from 12-15 nanometers and having a surface area of 140.5 m2/g includes titanium oxide, graphene oxide and silver, the silver ranging from about 2 weight % to 10 weight %. The method of preparation includes introducing sol gel to a microwave irradiation to prepare an irradiated sample of TiO2-graphene oxide sample, wherein the sol gel includes TiO2 containing gel along with graphene containing sol, followed by adding AgNO3 solution to the TiO2-graphene oxide sample for preparing a TiO2-graphene-silver hybrid suspension. The TiO2-graphene-silver hybrid suspension undergoes microwave irradiation to prepare dried TiO2-graphene-silver hybrid composite.
